You mean open the hard drive cover? That is the worst thing!!! Once it is open, it is goner! Can't save it, period. Reason? When you open the hard drive, all of the dust goes into it and that is a BIG NO-NO! To open it up, must clean the outside hard drive VERY VERY VERY good, and has to be in super clean room. The room that has almost NO dust in there, that is where you can open it up. Anyway, to better understand why, the gap between the read/write head and the disc looks as if it already touch it, but nope! It does not touch it... only about .0005mm, and the average size of dust is about .0075mm and it can get stuck between the read/write head and the disc and will stratch the disc, in turn ruin the disc! So, NEVER NEVER NEVER attempt to open hard drive to fix it, otherwise your gonna make it alot worse than it is.
